“…For example, increased growth after fire in a cerrado tree species was correlated with a significant increase in gall midge densities (Vieira et al 1996), and similar results were found for willow resprouts and their grasshopper herbivores after fire (Stein et al 1992). In the present study site, fire resulted in higher abundances of leaf-cutter ant colonies (Atta spp.…”

Interactions between repeated fire, nutrients, and insect herbivores affect the recovery of diversity in the southern Amazon

Surface fires burn extensive areas of tropical forests each year, altering resource availability, biotic interactions, and, ultimately, plant diversity. In transitional forest between the Brazilian cerrado (savanna) and high stature Amazon forest, we took advantage of a long-term fire experiment to establish a factorial study of the interactions between fire, nutrient availability, and herbivory on early plant regeneration. Overall, five annual burns reduced the number and diversity of regenerating stems. Community composition changed substantially after repeated fires, and species common in the cerrado became more abundant. The number of recruits and their diversity were reduced in the burned area, but burned plots closed to herbivores with nitrogen additions had a 14 % increase in recruitment. Diversity of recruits also increased up to 50 % in burned plots when nitrogen was added. Phosphorus additions were related to an increase in species evenness in burned plots open to herbivores. Herbivory reduced seedling survival overall and increased diversity in burned plots when nutrients were added. This last result supports our hypothesis that positive relationships between herbivore presence and diversity would be strongest in treatments that favor herbivory—in this case herbivory was higher in burned plots which were initially lower in diversity. Regenerating seedlings in less diverse plots were likely more apparent to herbivores, enabling increased herbivory and a stronger signal of negative density dependence

“…In addition, shoot development can be influenced by other environmental factors, e.g., fire (Noble, 1982;Christensen & Abbott, 1989) (see also Stein et al, 1992). The influence of weather and fire on the quality of eucalypt shoots depends upon spatial and temporal occurrences of events and plants and results in high quality shoots being typically rare throughout the entire distribution of any particular Amorbus species.…”

Species of Amorbus Dallas (Hemiptera: Coreidae) appear to exhibit a tight link between oviposition preference and nymphal performance: females apparently select vigorous plant modules to facilitate the development of their offspring. Such behaviour suggests that these insects should exhibit population dynamics consistent with the latent classification proposed by Price et al. (1990). While this empirical hypothesis is intuitively appealing it does not appear to incorporate current population dynamics theory. Berryman's ecodynamics (1992) offers the potential to describe a species' population dynamics which is grounded in a quantitative theoretical framework. The population ecology of Amorbus species from Australia is considered in relation to these hypotheses.

“…Although numerous studies have demonstrated that severe plant damage increases the abundance of herbivorous insects (Danell and Huss-Danell 1985, Stein et al 1992, Olofsson and Strengbom 2000, Spiller and Agrawal 2003, Nakamura et al 2005, far fewer have shown that resprouting enhances species diversity (Bailey and Whitham 2003, Nakamura et al 2006, Utsumi et al 2009). We demonstrated that species diversity and composition of pre-dispersal seed predators are affected by clipping.…”

“…Compensation, the degree of tolerance exhibited by plants (Strauss and Agrawal 1999), operates by way of a suite of complex and interrelated mechanisms, including high photosynthetic and growth rates, and/or branching following the release from apical dominance (Stein et al 1992, Meyer 1998, Lortie and Aarssen 2000. Plants may compensate for damage by producing more or larger structures, which may also attain greater total biomass than undamaged ones (Belsky 1986, Maschinski andWhitham 1989).…”

Abstract. Severe damage often provokes compensatory resprouting of plants, which commonly modify plant morphological and phenological traits. Rapid plant growth often results in poorly defended nutrient-rich foliage, which is more susceptible to foliar-chewing herbivores. It is less known how other guilds of arthropods are affected by plant regrowth. We tested the hypotheses that clipping-induced resprouting and nutrient availability, separately and in combination, would (1) influence plant traits, (2) benefit chewing herbivores, sapsuckers, gallers, and pre-dispersal seed predators, and (3) cascade up to the third trophic level by positively affecting herbivores. Resprouted plants were morphologically and phenologically different from undamaged plants; as a result, seed predation, infestation rate, richness, and diversity of seed predators increased, and species composition was altered. Leaf consumption by chewing herbivores was four times higher on resprouted plants. The number of galls decreased, whereas the abundance of sap-sucking and leaf-chewing insects was not affected. The incidence of predators and parasitoids was also higher on resprouted plants and on plants with nutrients added, but the increase was less pronounced compared to the herbivores they feed on. Thus, the effects of resprouting, contingent on nutrient availability, can propagate simultaneously through two independent tri-trophic level pathways.
